Michael Sandel在第一課就開宗明義：「沒錯，這些問題是被辯論了很久，但之所以它們持續出現而且貫徹始終，也許代表了雖然是一些不可能的問題，但也是一些不能逃避的問題。」 *
如今社會道德淪喪，既然有教授樂於講授道德和哲學，而且是免費遙距教育，不妨一看為何這麼火紅。
李敏一言
思考「數獨」成功的話會令你感覺圓滿，思考哲學問題是相反的感覺。
* It's true that these questions have been debated for a very long time, but the very fact that they have recurred and persisted, may suggest that though they are impossible in one sense, they are unavoidable in another.
